Members of this family contain two conserved disulphide bridges, these are joined 1-4 and 2-3. Members of this family have an amino terminal propeptide which is cleaved to give the active protease domain. All other linked domains are found to the carboxyl terminus of this domain. This family includes: Astacin Swiss:P07584, a digestive enzyme from Crayfish. Meprin, Swiss:Q16819, a multiple domain membrane component that is constructed from a homologous alpha and beta chain. Proteins involved in morphogenesis such as Swiss:P13497, and Tolloid from drosophila Swiss:P25723.

Typically, either the N-terminal or C-terminal end is very divergent. But splitting into two domains would make very short families. All members except Swiss:Q03196 and Swiss:Q10993 are found. Pfam:PF00666 are related to this family but have not been included.
